Recycling the Sound of Music

The village of Catuera in Paraguay is literally built on a garbage dump that grows by more than 1,500 tons of solid waste each day. The people, including children, who live around this trash heap survive by sorting and recycling the garbage.

Several years ago, Favio Chavez, an ecological technician who worked at the landfill, befriended the poor scavenger families and became acutely aware that the children who worked on the trash pile yearned for something uplifting in their lives. He decided to share his love of playing music by teaching the children to play instruments. At first, Chavez used his own musical instruments to teach them, but so many children wanted to learn that he tried cobbling violins and cellos out of oil cans, jars, scrap wood, forks and other junk to give them something to play, After about four years of experimenting, Chavez and his team began discovering which materials created the best sound. The result is a youth orchestra, now 30 members strong, that produces the sweetest sounds from their recycled instruments. Recently their story has been turned into a documentary, directed by Graham Townsley. It’s an inspiration on many levels.

The Scoop on Poop

It’s tempting to turn this story into a string of crappy jokes, but the subject is no laughing matter. In Seattle this week, the Bill and Melinda Gates Foundation hosted a two-day “Reinvent the Toilet” fair, attended by scientists and entrepreneurs eager to demonstrate their wares. To put these inventions to a credible test, the Foundation placed an order for about 50 gallons of fake poop. The Gates also offered over $3 million research grants, which were part of a $370 million grant initiative to improve the world’s water, sanitation and hygiene.

According to the Foundation, four out of every ten people around the world have no place “to go.” That adds up to 2.6 billion people without access to a toilet. Poor sanitation results in half the world’s hospitalizations. It is the cause of 2.5 million cases of diarrhea in children under five and 1.5 million child deaths a year, according to a United Nations report. Even in industrialized nations, the amount of water consumed each flush puts pressure on the environment.

In sponsoring this cash competition to come up with a toilet of the future, the Gates Foundation set several requirements. The toilet must operate without running water, electricity or a septic system. It must not discharge pollutants, preferably capture energy or other resources, and operate at a cost of 5 cents a day.

This week’s toilet fair resulted in some very promising solutions, including using soldier fly larvae to process human waste to produce animal feed. Other approaches turn human waste into charcoal and fuel. In announcing the cash prizes for the best designs, Bill Gates said, “If we apply creative thinking to everyday challenges, such as dealing with human waste, we can fix some of the world’s toughest challenges.”

Although coming up with the next toilet isn’t as glamorous as, say, creating the next Eames chair, it shows that design runs deeper than cosmetic solutions.
